Abstract

Abstract: Faced with the problem of the drawing back of moving contacts caused by the rebounding of a group of cylinders of ZYJ7 + SH6 electro-hydraulic switch machine, this paper analyzes and deals with the problem by focusing on the circuits and interlocking. The real causes of the problem are found through the analysis and discussion of the continuous operation circuit of the switch machine and the mechanical characteristics of outdoor turnout action.

Key words: electro-hydraulic switch machine, drawing back of moving contacts, oil cylinder rebound, motor reverse

摘要： 结合一组ZYJ7+SH6型电液转辙机油缸反弹造成动接点回退问题，从电路和联锁方面进行分析与处理，通过对ZYJ7+SH6型电液转辙机续操电路和室外道岔动作机械特性分析和探讨，找到动接点回退的真实原因。
